IMPROVEMENT 1N Brame PRESSES.

TO ALL WHOM IT MAY CONCERN:

Be it known that I, MQSES D. CMHEEK, of. Clarendon, inthe county of Monroe, -and State of Arkansas, have invented a new and useful- Improvement in Baling Presses; andy I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, in which- Figure l is an end elevation of my press. I i

Figure 2 is a lvertical longitudinal Section of the lower part, showing the operative mechanism.

Figure 3 is a horizoni'al section ou the line 11 rc, showing in plan viewv the same parts as those represented in fig. 2.

My invention relates to thatclass of standingpresses operated by screw power, and adapted to the baling of cotton and likepurposes; and it consists, first, iu the construction of the nut-whe'ols,'whereby greater steadiness and uniformity of action are attained than hitherto; second, in the mnthedvand arrangementof the mechanism for attaining greater speedwhen backing down than when running up the -follower; third, inthe general arrangement of the machinery, securing great compactness and simplicity; fourth, in the construction Aof the hinged cover of the baler. l Y

That others may understand the construction and,l operation of my machine, I .will describe itparticularly.'

A A are the timbers of the frame of my press. The said frame is tied together at the' corners by the rods IE B, which, by their tensile strength, resistthepressure of the, screws C C While in the operation' of vcompressing a bale of cotton or other material. The pressure-chamber is at the upper part of the frame, .directly under thelliinged cover D.; the` follower or platen E, resting upon and secured tothe heads ofthe screws@ C, and forced up by' them as they rise. The screws C C are' prevented from turning by their attachment to the foll'ower n.

I will now liarticularly describe the operative machinery, .and those part-s of it`embracing my invention. 'The nut-wheels I*1 F rest upon the lower-timbers of the frame. They are constructed with hubs, G G, which aro turned upon their outer sidcsso as to form journals, upon which vthe nut-wheelsare toturn. lTliese'hubs G G are suzleiently large to permit the screws-GC to pass down through thei'rcentres. The lower end of the hub G projects into a'corresponding' deprcssionin plate, H, which is secured to the lower timber or head of the frame A. This depression in the plate H forms a bearing orbox, by whiclrthe wheel F ally, and it also forms a step to receive the downward pressure incident to the act-ion of the serew Gwlien'in operatiou.- The upper end of the hub G lhas its bearing in the plate I, which passes from the framework on one side of the 'frame-A to the framework on the otherside of the same, so that the wheel F is supported in bearing on its upper and lower side, and is thereby .securely retained in place. But in order to prevent the action and `great pressure ofl the screw C from affect-ing these bearings by any tendency to wear more upon one side than another, and thus get out of line to the detriment of the operation of the apparatus, construct the nuts of the wheelsl F ns follows: I bore the Vhub G from its upper yend larger than the greatest diameter ofthe screw C, and continue the bore oi' this size until nearly or quite in line u'itlrtlie under sident' the wheel, as shown at J, fig. From this point I continue the bore' through to the lower end of G, of a size proper for a female thread, as at K, to correspond with the male thread of C. By these means, .as will be evident, the pressure of the screw C upon the wheel F is brought close down togthe step II, and the upper end of the hub G does not touch the is retained in place laterscrew, and. the tendency to. work out oi'v line is reduced to the minimum. Between the wheels F F is the pinion L, which has its pivot stepped in the bedoi` the frame A, as shown in tig. 2. It gears withvb'oth wheels F and F, and therefore moves lthem simultaneously whether forward or backward. Upon" the upper side of' the pinion L are the two bevel-gears and N, upon the saine centre'as L.. The bevel-gear N is considerably smaller than M, and is used to drive the pinion and nut-wheels when the press is being backed down when greater speed is desirable; and the bevel M is used when running up to compress the bale. The shaft of L, M, and N-has its upper bearings in the plate I. Transversely across the centre of the machine, andjust above the plate I, is the 'driving-shaft O. Upon it are mounted the beVel-pinicnsP and Q, both 0i' which have clutch-collars', and are loose upon said shaft, but are secured as desired by bringing into proper gear and up to the cluteh-pin Ri These movemeutsoiv` the lriviug-pinions P and Q are effected by the clutch-lever S and the stirrup T which lconnects them to the clutch-lever. By moving the clutch-lever the driving powerumay be thrown in connection with the bevel-wheel M, which runsthe screws up with a slow motion and great power; or it may be thrownin connection with the small gear N, which reverses the motion of the screws C, and runs them down rapidly; or, by leaving the lever at-apoint midway between these connections, the driving power is disconnected entirely, and the screws will remain at rest. A key, Uforan equivalent (le\'ice,qiassiiig through the hole in the -Vlever into one of the holes V, retains the lever in either position as desired.V "'lhe cover D isattachedto the lower side of the heavy straps W, which are jointed at one end to the upper ends' of' one pair of the tie-rods B, and are secured at their other ends to the upper ends 'of the other pair of tie-rods. They are thus secured by passingthe upper ends of the tie-rods through lperforations in the ends ot' the straps, and by then inserting keys through proper orifices in the upper ends of the rods above the straps. This construction is clearly shown 'in fig. l. By it secure equal strengthin thecover and all other parts of the frame, for, during the operation of compressing a bale, the cover supported and retained directly by the same tie-rods which support and retain the base of the frame and the operative machinery in prop'er place. The sides o i" the pressure-box are made removable, as is usual, `so as to permit the bale to be tied.

The advantages of my machine are, first, simplicity and conipactness of structure', with facility of operation, and the great power derived from the two screws; second', increased steadiness and uniformity `of action, due to the construction of Vthe nut-wheels, as described; and, third, the convenience and facility of filling through the open top without the undue increase of the weight of the same, which wouid be necessary were the tie-rods B'not directly connected to the cover.

Havingsr described my machine, what I claim as new, and desire to securevby Letters Patent, is-

rhe nut-wheel F, constructed with the hub G and the bored recess J, substantially as and for the purpose set forth. i

The nut-wheels F, pinion L, provided with the two bevel-gears M and N, and the driving-pinions P and Q, combined, arranged, and operated substantially as set forth.

' The lever S and stirrup 'l in combination with the beitel-gears P and Q, substantially as set forth.
